xbox ports arent open help?

[metalbew 2]

So after hours of research and finally getting it i have open vpn on my dd-wrt router in ip passthrough on motorola nvg589 hub

 

everything is working, decent speed, changed ip, i connected my xbox to the dd-wrt and port forwarded the xbox ports but when i test them it says my ports arent open

 

anyone have some advice

i got everything working but i can only get unrestricted nat when using upnp or port forwarding, when i use ip tables i still get strict nat and when i play a game i get kicked offline, i never had this problem using my pc with ics, i got a new router hoping to get connection like i would without vpn

 

if anyone can help that would be great
